Since we are breaking a lot of stuff in 6.0, at least with
Unicode_semantics=On I am wondering if it may not be time to break some
more stuff and do a bit of spring cleaning. It would mean many apps
would need some work to work on PHP 6, but at the same time I think it
is work people would welcome since it would mostly involve removing
hacks instead of adding them. And yes, I know this is pretty
controversial, so take a few deep breaths before replying, please.
1. Remove register_globals completely
2. Remove magic_quotes_*
3. Add input filter extension which will include a mechanism for
application developers to very easily turn it off which would swap
the raw GPC arrays back in case the site had it turned on by default.
4. Include an opcode cache by default. A lot of work has gone into
pecl/apc recently, but I am not hung up on which one goes in.
5. Remove safe_mode and focus on open_basedir
6. Remove some stuff that has been marked deprecated since PHP 3/4
A couple of others that we could consider, but I don't actually think
wins us much apart from academic purity (which I have never been all
that keen on) are:
7. Make identifiers case-sensitive
8. Remove various function aliases
